Versuchsvorschrift

To 2-chloro-5-(chlorosulfonyl)benzoic acid (0.51 g, 2.0 mmol) was added dichloromethane (10 mL), oxalyl chloride (1.5 mL) and one small drop of N,N-dimethylformamide. The mixture was stirred at room temperature for 3 days. The mixture was then concentrated until oxalyl chloride was gone to give 2-chloro-5-(chlorosulfonyl)benzoyl chloride. The residue was used without purification.
